METHOD OF AND APPARATUS FOR APPLYING CAKE REENFORCEMENTS Filed July 27, 1926 n-uan to z FFP/i/V/f W YOU/VG Patented- Nov. 4, 1930 UNITED sures- Em r w. YOUNG, or vEaoNA,'NEw JERSEY IE'I'HOD AND APPARATUS FOR APPLYING CAKE BEENFORCEMENTS Application filed July 27, 1926. Serial No. 125,261.

In a copending ap lication b Arthur Wright and Frank Young, 115,481, filed June '12, 1926, there is disclosed a reenforcement for deposit's,'such as filter cake,'comprising, in the preferred embod1- ment, a plurality ofseparate, endless, substantially flexible members about which the deposit is built up by the migratlonthereto of solid particles in suspension in a liquid.

The present invention relates to reenforcements of the same general character. In the application of the reenforcement in situations say where the members are to be d1- rected about both a rotary deposit forming l5 device and a drying drum or other cyhndrical element, considerable difficulty is .experienced and much time and labor is involved in laying the strands in proper relative position and closing the. respective ends to form a continuous member. V

The present invention has for its object the facilitation of the application of a plurality of spaced strands about a rotary deposit forming instrumentality and other cylindrical units associated therewith and, the union of their respective ends to form continuous or endless members. Accordingly, a

' plurality of strands of the desired character are laid upon and secured to'a sheet in prop- 39 erly spaced and preferably parallel relation so that the sheet asa whole" may be caused'to encircle the associated: cylindrical elements until the edges are juxtaposed when the respective ends of the strands will meet and may be secured together. Thereafter the sheet may be removed leaving the endless strands in operative position on the machine. The invention also has to do with the article of manufacture which may be made of indeterminate length and cut to the desired lengthand dispensed for replacement of worn reenforcing members as occasion requires. In the preferred embodiment, the strands are glued to a-. sheet of textile or fibrous material, such as heavy paper, and a second sheet say of tissue paper is laid upon the strands for their protection.

The invention also seeks to provide a method of, and an instrumentality for, accomplishing the manufacture of the aforeerial No. 7

said article. Accordingly, a roll of fibrous material, say, is mounted adjacent an adhesive applying device to which a sheet of the material is led from the roll tohave the adhesive applied to one side thereof. 'A plurality of strands are then directed from a, plurality of spools and laid upon the treated side in the desired relation, a sheet, say of tissue paper,-being then directed, from a roll thereof, to the treated side of the first sheet upon whichthe strands have been applied. These and other objects of the invention and the means for their attainment will be more apparent from the following detailed description taken in connection with the accompanying drawings, illustrating preferred embodiments of the invention, in which:

Figure l is a View, in side elevation, showing one type of continuous filter and filter cake drying device to which the method of applying a filter cake reenforcement formed of separate continuous members is applicable.

Figure 2 is a plan view showing a fragmentary portion'of the article of manufacture'including the reenforcing medium comprised of separate spacedstrands serving as the vehicle by which the reenforcing medium isapplied to a cake or deposit forming instrumentality. v I

Figure 3 is a somewhat schematic view showing an instrumentality. by which the article of manufacture is made.

Figure 4 is'a detail View showing a fragmentary portion of the instrumentality illustrated in Figure 3, looking in the direction indicated by the arrows 4-4 in that figure. The reenforcement A fora deposit such as filter cake-comprises a plurality of separate, spaced, parallel and continuous or endless strands, such as are shown at a in'Figure 2 and which are adapted to be looped, asshown in Figure 1, about a cake forming instrumentality, say the continuous filter b, and another cylindrical element such as the drying drum 0 and/or a cakestripping roller (1 in the copending application. It will be readily appreciated that were a plurality of independent strands a individually looped and/or guide or idler rollers call as described about the cylindrical elements as shown and their respective ends tied to form continuous members, considerable time and efiort would be required and difiiculty experienced in se= lecting and the proper ends together.

This procedure is facilitated according to the resent invention by applying the strands in t e desired relation to a s act a of suitable material such as heavy paper and then looping the sheet with the strands applied as a.

. whole about the cylindrical elements until the I shown in Figure 2. After the respective ends are all tied together and a plurality of end less members are formed, the carrier layers of paper a and a may be readily removed as will be understood.

In Figure 3 there is illustrated an instrumentality by which the article shown in Figure 2 maybe made. The sheet of heavy paper a is formed in a roll at a from which it is drawn in the direction indicated by the arrow :1: through adhesive applying devices by which a suita le adhesive is applied to one side. Uplon this treated side 0 the sheet a, a plura. 'ty of the strands a are held by a comblike guide 9 to which they are fed, respectively, from a series of spools or reels k, the strands a being applied to the sheet by adjustable pressure rolls z and in order that the pressure rolls ma be protected from the ad esive a second s eet, say of tissue paper a is drawn from the roll a and directed through the pressure rolls i as shown, the

, completed article A coming out of the'rolls i and being reeled up into the roll A".

It will thus be seen that a method of ap plying a spaced continuous strandreenforcement to deposit forming devices has been y a vehicle of sheet form and applied all at once so that the respective ends may be united provided in which the strands are carried.

prisin a sheet of heavy paper, a plurality of stran an adhesive to removabl secure the strands to'one side of the sheet 1n redetermined s need and substantially para el relation, an a sheet of tissue paper overlying the strands and pasted thereto, and to the heavy paper. J

2. The method of applying a plurality of spaced strands in encircling relation about a cylindrical element which includes securing the strands in predetermined position upon a sheet, encircling the sheet so formed about the element, causin theends of the sheet to abut, securing toget er respective strands and removing the sheet. 7

3. The method of applying a plurality of spaced continuous, flexible strands in predetermined relation about a rotary filter and a cylindrical member which consists in disposing the strands in predetermined relation between sheets of fibrous material with the aid of adhesive, encircling a sheet of redetermined length about the filter and t ecylindrical member until the ends abut, securing together the proximate ends of the respective strands and removing the sheets of fibrous material.

4. As an article of manufacture, a vehicle for the application of spaced filter cake reenforcing strands to rotary drum filters comprising a sheet offibrous material, a plurality of separate spaced flexible strands and an adhesive to removably secure the strands to the sheet. a

5. As an article of manufacture, a vehicle for the application of'spaced filter cake reenforcing strands to rotary drum filters comprising a sheet of material, a plurality of separate spaced flexible reenforcing strands, an adhesive to removably secure the strands to the sheet and a second sheet overlyin said strands and said first named sheet an removably secured to said-strands and to said .first sheet.

in a convenient manner without confusion or mistake. A method of instrumentality for manufacturing the vihicle has also been provided.

Various modifications will occur to those skilled in the art in the form and composition of the vehicle for the reenforcement as well as the uses to which it may be put and in the method of its manufacture as well as in the instrumentality by which it is made and no limitation is intended by the foregoing phraseology or accompanying drawings beyond that set forth in the appended claims.
